Diameter of Sphere is 50. (Diagonal of cuboid = Diameter of the sphere) Diagonal of cubiod, sq.rt(l^2 + h^2 + b^2) = 50,
Also total surface area 2(lh+lb+bh) = 4896
we know (l+b+h)^2 = l^2 + b^2 + h^2 + 2lb + 2bh+ 2hl
just substitute the values, you will get l+b+h = 86
Sum of edges = 4(l+b+h) = 4*86 = 344.
